No, the alternator will not charge the battery with the negative terminal loose.
Bad alternator, voltage regulator, or battery. Also a loose or corroded cable or bad cable.
Defective alternator, dead cell in battery, something on pulling power from the battery when the vehicle is idle, corroded battery cable connections, or loose alternator drive belt.
If the loose cable is the main one from the negative side of the battery, then everything will flicker simultaneously with the key on and the engine stopped. When the engine is running, the alternator will keep things energized. If you have a loose groung cable on one particular accessory, only that accessory will flicker or just remain off.
The negative battery cable will short out if it is loose or corroded. Check both ends of the battery cable for corrosion. Make sure both ends are tight.
It means something is wrong with your charging system. Can be a loose of corroded battery cable, defective alternator or a battery with a dead short.
Corroded or loose battery connections, loose alternator drive belt, defective alternator, or dead cell in the battery.
all alternators require battery power to operate.
I assume you're asking how can you tell which is positive and which is negative? The red cable is positive in the black cable is negative. But if they are not color-coded the positive battery post is slightly larger than the negative battery post. If you try to connect the negative cable to the positive post it would be a tight fit and if you connect the positive cable to the negative post it would be loose.
Yes, a loose battery cable will prevent the alternator from charging the battery. The drain on the battery is not caused by the engine not running unless an accessory is left on. Most likely, the drain is caused by accessories (radio, lights, etc) while the engine is running due to the battery not receiving its charge from the alternator and then not having enough charge left to start the engine.
first unhook the battery cables and then take the alternator belt loose and then take the 3 bolts out that hold the alternator on and take the wiring harness out of the alternator and the red battery cable off and it's out.
Yes. If it is loose on the side that comes from that alternator, then the alt. is not getting the opportunity to charge the battery. So basically you're running your car on pure battery and it will go dead accordingly
